Biosynthesis of Fe doped ZnO nanoparticles using Berberis thunbergii extract

Bio-mediated synthesis of metal oxide nanoparticles (NPs) using plant extract is a promising alternative of traditional chemical synthesis. The present study focus on green chemistry in the synthesis of Fe doped ZnO NPs by Zinc nitrate, ferric chloride and utilizing the bio components of leaves and fruits extract of Berberis thunbergii. The structural, morphological, optical and colloidal properties of the synthesized NPs have been confirmed by X-rey Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-rey (EDX), Diffuse Reflectance Spectroscopy (DRS), Fouier transform Infrared (FT-IR) and Dynamic Light Scattering (DLS). The structural properties were analyzed by XRD and the results showed that the prepared sample is in hexagonal wurtzite structure with secondary phase of FCC structure of Fe3O4. observations using SEM show the formation of nanoparticles with remarkable morphologies. The presence of zinc, oxygen and iron elements of Fe doped ZnO NPs confirmed by EDX pattern. DRS studies indicate that absorption in the visible light region increase by doping Fe and DLS analysis indicate that Fe doped ZnO NPs have less polydispersity index (PDI) and major zeta potential compared with ZnO NPs.
